Official state statistics, based on micro census:
https://www.statistik-bw.de/Familie/Einkommenslagen/F-NE-m-K.jsp
For 2016 it's 3454 median net income with two children for all family types (single-parent*, two-parent married, two-parent non-married, two-parent same-sex partnerships) for primary earners between age 35 and 45. With the Kindergeld on top - 408 Euro for two kids now - we're at 3862.
* that's important, as it markedly drives down the median - only 17% of single-parent families with primary earners in that age group have net incomes of more than 3200 Euro.

The average income of families in Baden-Württemberg was around 4,000€ net for 2017. That's also virtually equivalent to the amount where in Baden-Württemberg a family of four can apply for state assistance with rent - and yes, our caps for that are quite high in comparison to other German states.
Karlsruhe is relatively cheap as rents go, at least when compared to other cities in Baden-Württemberg.

Especially given that the Klingons were modelled off the Soviet Union, with broad hints at politically representing Communist China at the time in '66.
The "reasoning" for the Arab connection (other than pure conjecture based off of who espouses it, namely certain - mostly American - religious groups) likely comes from a very European interpretation of the script of the first TOS episode with Klingons appearing, in which their looks were termed "Oriental". This of course referred to East Asians, not Arabs though.

From HIS ? It's at the other end of town virtually, with training at Sportzentrum Süd (outdoor) and both there and at various schools around Kirchheim (indoor).
Physically located closest to HIS would be TSV Wieblingen, with their outdoor training grounds next to the SRH college two tram stops away. Although in which area of Heidelberg OP would live then should be more important in my opinion...

If both partners live in Germany then German law is applied by default in a divorce, unless both partners choose to have foreign law applied, or have pre-decided such explicitly as part of a marriage contract (foreign law as in that of the country of nationality or the country of residence of either of the partners). And yes, they do "deliver the legal systems of 200+ nations" in such cases.

The only useful functionality that i see is that Deutsche Post is offering PostIdent using eID. But: Only if the company that buys the PostIdent service for identifying customers selects to use that.
As perhaps interesting variants there's also a few cloud services that offer authentication through eID as a possible option.
Applications are listed here - though the German version of that particular page has a lot more. Offhand compared to back then a couple banks and insurance companies dropped eID support.

With regard to mosquitoes, it used to be a whole lot worse until they started the annual campaigns against them about 20 years ago - killing billions every year with bio-warfare bombs dropped from helos in the Altrhein areas south of Mannheim.

Over here that's literal too.
90.9% of all public transport trips here in the Rhine-Neckar area are done using passes instead of individual payment tickets - out of about 310 million passengers. Which is one of the highest rates in Germany.
Individual payment is also used almost exclusively in the cities here, i.e. spontaneous urban travelling such as by tourists. In the countryside the quota of passengers using passes is above 99% (!).
